Oil pump pressure
(Courtesy of Ryan Maroszek owner of "bad news Celica" on YouTube)
"All pressure is max pressure when oil is up to temp.
3S-GTE=55-60psi
VW 1.8t runs=75psi
Honda B series=80psi
4G63=75-80psi
2JZ=70psi
SR20DET=80psi
As you can see the 3S-GTE runs the lowest pressure.
Did some looking at this too. The oil pump speed vs crank speed.
You can see the 3S-GTE pump.is the only one that spins slower than the crank."
3S-GTE (2nd gen)=23/27=.8519
3S-GTE (3rd gen)=23/25=.92
2JZ= 1
Honda B Series= 1
Honda K Series = 1.6
SR20= 1
4G63= 1.333
